Structure of the talk
Fisheries management
“All ecological models are wrong, but some are useful.” ( Stouffer, D. B., 2019. J Anim Ecol 88 (2), 192-195).
Maximum Sustainable Yield
Modified from May et al., 1979. Science, 205 (4403), 267-277.
Nash equilibrium?
From Farcas, A. and Rossberg, A. G. 2016.. ICES J. Mar. Sci., 73 (10), 2499-2508.
Model selection
To play around with the package go to NOAA-EDAB/Rpath.
Rpath vs ECOPATH
Rsim vs ECOSIM
↓ \(\overline{Error(\%)}=-0.025\) with no external abiotic forcing (e.g. fishing effort or egg production time series).
Medium term goals
- To wrap a 2nd functional iteration of the
Rpathpackage; - To compute NE MSY solutions for the North Sea ecosystem with
Rpath2 (ecopaRth?)to assess tradeoffs between current management practices (i.e. single species management) and the so-called Ecosystem-Based Fisheries Management to ultimately find optimal mixtures of stocks; and - To, perhaps, evaluate the predictability of these optima and their required management intensity taking into consideration inherent uncertainties.
